[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] The following describes some embodiments of the present invention in conjunction with the accompanying drawings to provide a transformer withstand voltage testing mechanism.

[0024] Example 1:

[0025] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, provides a transformer withstand voltage test mechanism, including a base plate 100, an internal transmission component 200, an external transmission component 300, a synchronous gear 400, an internal probe mounting plate 500, an external probe mounting plate 600, a cylinder 700 and a test placement plate 800.

[0026] Specifically, the inner transmission assembly 200 includes an inner slider 201 connected to the top of the base plate 100 by screws, an inner sliding shaft 202 inserted in the inner slider 201, and an inner rack 203 arranged outside the inner sliding shaft 202. When in use, the inner slider 201 has a limiting effect, so that the inner sliding shaft 202 can only move in a straight line, and the inner transmission assembly 200 can drive the outer transmission assembly 300 to move through the synchronous gear 400 for testing.

[0027] Specifically, the external transmission assembly 300 includes an outer slider 301 connected to the top of the base plate 100 by screws, an outer sliding shaft 302 inserted in the outer slider 301, and an outer rack 303 arranged outside the outer sliding shaft 302. The outer slider 301 has the same structure as the inner slider 201. When in use, the outer slider 301 has a limiting effect, so that the outer sliding shaft 302 can only move in a straight line, and the external transmission assembly 300 can drive the outer probe mounting plate 600 to move for testing.

[0028] Specifically, the synchronous gear 400 bearing is connected to the top of the base plate 100 and is meshed with the inner rack 203 and the outer rack 303. When in use, the cylinder 700 extends to drive the inner probe mounting plate 500 to move forward, and at the same time, the inner sliding shaft 202 connected to the inner probe mounting plate 500 moves forward, and the inner rack 203 installed on the inner sliding shaft 202 drives the synchronous gear 400 to rotate, and the synchronous gear 400 drives the outer rack 303. Then the outer sliding shaft 302 connected to the outer rack 303 and the outer probe mounting plate 600 installed on the outer sliding shaft 302 will move backward, so that the inner probe 501 and the outer probe 601 continue to approach the test placement plate 800 until they contact the transformer, and then they can move to complete the test.

[0029] It should be noted that the inner transmission assembly 200 and the adjacent outer transmission assembly 300 and the synchronous gear 400 are a group, and two groups are provided in total. When in use, the two groups can improve stability and facilitate testing.

[0030] Specifically, the inner probe mounting plate 500 is arranged at the front end of the inner sliding shaft 202, and the inner probe 501 is arranged on the inner probe mounting plate 500. Two linear bearings 502 are provided on the inner probe mounting plate 500. The two linear bearings 502 are both slidably connected to the outer sliding shaft 302. When in use, the two linear bearings 502 facilitate the sliding of the outer sliding shaft 302, thereby preventing the inner probe mounting plate 500 from affecting the outer sliding shaft 302 and driving the outer probe mounting plate 600.

[0031] Specifically, the outer probe mounting plate 600 is arranged on the outer sliding shaft 302, and the outer probe 601 is arranged on the outer probe mounting plate 600. When in use, the outer transmission assembly 300 can drive the outer probe mounting plate 600 to move so that

[0032] Furthermore, the external probe 601 has the same structure as the internal probe 501. There are several external probes 601 and several internal probes 501. Several external probes 601 correspond to several internal probes 501 one by one. When in use, several external probes 601 and several internal probes 501 can cooperate to test several transformers with high efficiency.

[0033] Specifically, the cylinder 700 is arranged on the base plate 100 and the inner probe mounting plate 500. When in use, the cylinder 700 is a power source, which can drive the inner probe mounting plate 500 and the outer probe mounting plate 600 to continuously move closer or farther away through the inner transmission component 200, the outer transmission component 300 and the synchronous gear 400 for testing.

[0034] Specifically, the test placement plate 800 is screwed to the top of the substrate 100. Two circular holes 801 are opened on the test placement plate 800. The two circular holes 801 are symmetrically distributed. When in use, the two circular holes 801 allow the outer sliding shaft 302 to pass through the test placement plate 800, making it convenient for the outer sliding shaft 302 to drive the outer probe mounting plate 600 to move.

[0035] The working principle and usage process of the present invention are as follows: when in use, the transformer can be placed on the test placement plate 800, and then the cylinder 700 is extended to drive the inner probe mounting plate 500 to move forward, and at the same time, the inner sliding shaft 202 connected to the inner probe mounting plate 500 moves forward, and the inner rack 203 installed on the inner sliding shaft 202 drives the synchronous gear 400 to rotate, and the synchronous gear 400 drives the outer rack 303, and then the outer sliding shaft 302 connected to the outer rack 303 and the outer probe mounting plate 600 installed on the outer sliding shaft 302 will move backward, so that the inner probe 501 and the outer probe 601 continue to approach the test placement plate 800 until they contact the transformer, and then they can be moved to complete the test. The entire test structure is simple and efficient, with low production cost. The product model can be quickly switched by replacing the test placement plate 800 and the probe mounting plate, and other types of tests can be completed in conjunction with other detection equipment.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
